Study on the Application of GIS in the Same Frequency and Phase AC Voltage Test Method

摘要

In order to carry out comprehensive analysis and study on the application of GIS in the same frequency and phase AC voltage withstand test method, this paper studied the same frequency and phase AC voltage withstand test of GIS, briefly described the test device and the connection principle of same frequency and phase AC GIS voltage test, and analyzed the voltage variation of GIS device bus isolation switch port in detail. Hope to provide reference and help for the use of GIS equipment in AC voltage test. The traditional GIS AC voltage withstand test requires the whole performance of the power failure of adjacent to the test part and the operation part to finish it successfully. However, the same frequency and phase AC withstand voltage test of GIS refers to the same frequency and phase AC withstand voltage test of expansion or maintenance of the interval part of GIS equipment under the condition of keeping the adjacent test section and running part without power outage. Compared with the traditional test method, the test method of GIS with the same frequency and phase has some significant and outstanding advantages.
